Disk centering device |
摘要 |
The disk centering device of the invention includes: a turntable for retaining an information recording disk which has a center hole and is placed on a placing surface so that the disk can rotate around a rotation axis thereof; and a centering unit including a plurality of centering portions coming into contact with a periphery of the center hole and a plurality of resilient portions, each of which is connected with a corresponding one of the plurality of centering portions for supporting the centering portion so that the centering portion can be resiliently displaced in a radial direction of the information recording disk. In the disk centering device, the turntable includes regulating faces for regulating positions of the centering portions in a state where the centering portions are resiliently displaced in the radial direction as a result of a contact between the centering portions and the regulating faces, and each of the centering portions is in contact with the periphery of the center hole at a disk contact part which is located at a position more distant from the resilient portion than the regulating face.
